This paper, a comparative study of the psychotherapy of psychoses, includes a historical review of the subject, beginning with Freud's theories on the nature of psychoses and describing the evolution of theoretical thinking and therapeutic application. The fundamental principles of Fromm-Reichmann, Sechehaye, and Rosen are systematically reviewed. The author favors Rosen's 'direct analysis' over Fromm-Reichmann's 'intensive psychotherapy' and Sechehaye's 'symbolic realization'. Rosen's method appears to produce better results, to meet better the needs of the patient, and to permit more participation in the psychosis and contact with the unconscious; it seems, moreover, to be more systematic.
